I had this same exact problem with my Cherokee.
$450 later it turns out that the $12 gas cap was the problem.
Don't ask me why, I don't know but my mechanic and I stood there and said we replaced everything but the gas cap. So we replaced the gas cap. Haven't had a problem since.
My sentra also had a similar problem that all of the sudden disappeared after I steam cleaned the engine bay. Not sure why but all I can figure is that there was some dirt or something causing a bad contact on a sensor.
Hope this helps.
